Earth and Space Review

Students in a science class in Marfa, Texas, made a poster with a diagram to represent a seasonal change in the Northern Hemisphere. Which statement best describes conditions for Earth as Position 1 in the diagram?

• There are an equal number of hours of daylight and nighttime in the Northern Hemisphere, and the North Pole is tilted away from the sun.

• The Northern Hemisphere has the fewest hours of daylight, and Earth's axis does not tilt at this position.

• There are an equal number of hours of daylight and nighttime in the Northern Hemisphere because Earth's axis is not tilted in this position.

• The Northern Hemisphere has the fewest hours of daylight, and the North Pole is tilted away from the sun.

Which of these changes would likely occur if the rate of Earth's rotation on its axis increased?

• the length of the seasons would be shorter

• the lengths of the seasons would be longer

• the length of a day would be shorter

• the length of a day would be longer

A student draws the model shown. Which of these best compares the conditions at Location X and Location Y?

• It is day at Location X and night at Location Y

• It is winter at Location X and summer at Location Y

• There are more hours of daylight at Location X than at Location Y

• The moon is brighter when viewed from Location X than when viewed from Location Y

A student models moon phases. She holds a foam ball on a stick in front of her body and then stands in front of a light as shown. The student uses herself to represent Earth. She turns her body slowly to represent four different moon phases. Which numbered diagram represents the student modeling a full moon?

• Diagram 1

• Diagram 2

• Diagram 3

• Diagram 4

Why does the Sun appear to move across the sky during the day?

• Because the Sun orbits the Earth

• Because the Earth is rotating on its axis

• Because the Earth is moving closer to the Sun

• Because the Moon is moving in front of the Sun

What would happen if the Earth stopped rotating?

• We would experience constant daylight or darkness, depending on which side of the Earth you are on.

• The seasons would change more rapidly.

• The Earth would orbit the Sun faster.

• The Moon would fall out of orbit.

Why do we experience different seasons on Earth?

• Because of the Earth's rotation on its axis

• Due to the Earth's orbit around the Sun

• Because of the tilt of the Earth's axis as it orbits the Sun

• Due to the distance between the Earth and the Sun changing
